Philadelphia Archbishop Charles Chaput Wednesday urged prayers for all affected by the Amtrak train derailment in the city's Port Richmond neighborhood that left at least six people dead and injured more than 200 others.

"I urge all people of goodwill to join me in extending prayerful condolences to those mourning the sudden loss of a loved one and in asking the Lord to bring healing to all those suffering physical and emotional anguish in the wake of this incident," he said in a statement.

The world's bishops, priests and deacons need people's prayers and encouragement to continually deepen their relationship with Jesus and serve their community with love, Pope Francis said.

A minister of God who does not nourish his love for Christ, his church and his flock "inevitably ends up losing sight and an authentic sense of his service and the joy that comes from a deep communion with Jesus," he said.
